Is this Hypolimnas bolina jacintha or Hypolimnas bolina bolina. The upper hindwing submarginal band looks like a bolina but the white discal patch looks like that of the the female f-incommoda Jacintha. Helping a friend who shot this in Singapore. Janice 20160127.jpg
The two subspecies usually have their own localised colonies , though they will be mixing from time to time.
In the far future the population may become more homogeneous in Singapore.
I forgot you mentioned f-incommoda which is supposed to be a rare variant of ssp jacintha.
This has a bluish white FW cross band & a sullied bluish white HW patch. The HW submarginal spots are large as usual.
The example below mentioned as a perfect intermediate may be a variant of ssp jacintha. f-incommoda.
This gets very complicated, as it is difficult to determine the degree of crossing. http://3.bp.blogspot.com/_yzw2AzY2du...3-Federick.jpg
There is is an image of f-incommoda in C&P3, the older edition.
The FW cross band is bluish white & the HW patch is very narrow, sullied & bluish.

PS. As can be seen from the Indian website f-incommoda is unknown in India although the ssp is jacintha., & ssp bolina is absent.
The type specimen of incommoda was described by Butler from Malacca.
It is possible that f-incomoda is a hybrid of the two subspecies, jacintha & bolina.
It is classed as jacintha because it has large HW maginal & submarginal spots as in typical jacintha female.
Ssp bolina is the insular form ranging from Sundaland to Australia.
It would be the typical form when Sundaland is separated from the mainland. Ssp jacintha moves south after Malaya reconnects with the mainland & becomes the dominant form during colonial times.
In the Klang valley around KL the female is typical jacintha.
However, in many parts of p. Malaysia the form is ssp bolina.
